OBJECTIVE. TO compare primary care and traditional Internal Medicine reside
nts in their adherence to preventive medicine guidelines, performance in th
e management of chronic diseases, and utilization of resources.
DESIGN. Prospective cohort study.
SETTING. Urban Internal Medicine residency program.
PARTICIPANTS. Sixteen primary care and 137 traditional Internal Medicine re
sidents who took care of 6,307 patients (a total of 21,002 patient visits i
n a 1-year period).
MEASUREMENTS. Adherence to preventive medicine guidelines for the screening
of breast cancer, cervical cancer, hypercholesterolemia, and colon cancer;
admission rates among patients with asthma, chronic pulmonary disease, and
diabetes mellitus; four items in the management of diabetes; and resource
utilization including the costs for laboratory and radiology tests and numb
er of consultations.
RESULTS. Primary care residents, as compared with traditional residents, ad
hered to preventive medicine guidelines for a greater proportion of their p
atients for the following: breast cancer among women aged 52 to 75 years (6
1% vs. 54%, respectively, P = 0.05); cholesterol screening among patients a
ged 20 to 64 years (39% vs. 33%, P = 0.007); colon cancer among patients ol
der than 50 years (49% vs. 31%, P = 0.001); and cervical cancer among women
aged 20 to 64 years (36% vs. 31%, P = 0.03). There were no differences in
hospital admission rates for patients with diabetes or asthma. Total ambula
tory tare costs for tests, procedures, consults, and office visits were gre
ater far patients of primary care residents ($1,045 vs. $899, P = 0.0001),
although total costs per primary care visit were similar between the two pa
tient groups.
CONCLUSIONS. Primary care residents more closely adhered to preventive medi
cine guidelines but were similar to traditional residents in their manageme
nt of chronic diseases. Patients of primary care residents had greater ambu
latory care costs that were not entirely attributable to greater adherence
to preventive medicine guidelines.
